摘要
利用取代的苯甲醛和苯乙酸为原料,在三乙胺和乙酸酐作用下经Knoevenagel反应合成潜手性的不饱和酸中间体,再在钯-碳催化加氢作用下得到9种外消旋的2,3-二取代丙酸衍生物,所有化合物均经红外光谱和核磁共振氢谱表征其结构。
The prochiral unsaturated acid intermediates were prepared by the materials of substitutional benzaldehyde and phenylacetic acid with the participation of triethylamine and acetic anhydride through Knoevenagel reaction,and then nine racemic derivatives of 2,3-disubstituted propanoic acids were obtained on the condition of Pd-C catalytic hydrogenation.All compounds are characterized by IR spectrum and 1 H-NMR spectrum.
